Case Study

Based in South Africa, VUKA host live events and online webinars in the power, mining, retail and mobility industries. They also publish specialist magazines in the power and mining industries. Seeing rapid growth, and with hundreds of events per year, they had implemented HubSpot to streamline their sales process - and chose Invoice Stack to make invoicing simple across their organisation.

Complex billing made easy

VUKA’s billing structure is complex, with stage invoices, package contracts and different products billed at different times. In addition, there are a number of different entities set up in Xero, with different billing terms for each.

Before Invoice Stack - invoices were created manually inside Xero by the finance team, a time consuming process that duplicated data and risked errors. Now invoices are easy to create using the data that’s already in HubSpot.

Invoice Stack’s flexible billing structure meant that no matter how a deal is structured, it can be billed out easily, and we even set up some customisations for VUKA to automatically create invoices based on event dates.

Because Invoice Stack pulls data direct from multiple Xero accounts - as long as the correct Xero account is selected, specific billing terms, accounts and taxes are all assigned correctly.

Combining events data with billing data

Once invoices are created, the data is synced back to HubSpot on an ongoing basis into HubSpot deal properties. This allows for powerful reporting - for example, it’s easy to generate a HubSpot dashboard showing the deals and outstanding invoices, all grouped around a specific event, giving users an easy way to see the payment status for each deal.

Invoice Stack syncs data to over 15 different deal properties, and is updated every time an invoice in Xero is updated. This means you can plug the data into HubSpot workflows and reports, and combine it with your existing deal data, like event date, deal status or sector.

Passing the finance team test!


Before we used Invoice Stack, we needed to manually update our accounting system (Xero) with any information processed on our CRM system (Hubspot). Now, the process is fully automated!

Keeping the whole team happy when implementing processes is a key part of operational success. The finance team at VUKA were excited by the possibilities of Invoice Stack and how it could drive data quality improvements and save time. Invoice Stack has built-in controls for finance teams, such as an invoice approval step, and always uses Xero as a single source of truth.  In particular, the finance team love the ability to be able to track back from an invoice to find the deal and contract in HubSpot, which gives them real visibility on the context of the invoice.
